Cholera is caused by the Vibrio cholerae (V. cholerae) bacterium and presents with acute diarrhea and vomiting. If untreated, infected individuals may die due to dehydration. Cholera is a disease that most commonly affects countries with poor infrastructure and water sanitation. Despite efforts to control cholera in such countries, the disease persists. One such example is Haiti which has been experiencing …

Beyond Enlightenment: The Evolution Of Agency And The Modularity Of The Mind In A Post-Darwinian World, Derek Elliott

Electronic Theses and Dissertations

Working out of the social and philosophical revolutions from the Enlightenment, contemporary action theory has unwittingly inherited several Cartesian ideas regarding the human mind: that it is unified, rational, and transparent. As a result, we have for too long conceived of action as intimately bound up with reason such that to act at all is to act for a reason, leaving us with theoretical difficulties in accounting for the behavior of non-human animals as well as irrational behavior in human beings.

But rather than propose that such difficulties can be resolved by retreating to a pre-Enlightenment view of human nature, …

Discourses Of Deception: (Re)Examining America's War On Drugs, Benjamin Steven Boyce

Electronic Theses and Dissertations

America's war on drugs is a failed experiment that has caused more damage than it will ever prevent. From its original design to its contemporary manifestations, the war on drugs is a conflict that remains firmly rooted in white supremacy. In contemporary Western societies, the rhetoric of both political leaders and mass-mediated narratives becomes the raw material of subjective reality. Since the war on drugs began nearly a century ago, the spectacle of mass media has been consistently utilized by white political elites as a vehicle of misinformation - as a well-oiled machine for spreading the false social narrative that …

Characterizing Reactive Glutamines In Fibrinogen And Elucidating Factor Xiii Substrate Specificity., Kelly Njine Mouapi

Electronic Theses and Dissertations

Fibrinogen is the most abundant protein involved in blood coagulation and has been associated with many pathological implications in cardiovascular disease. At the final stages of blood clot formation, the transglutaminase Factor XIIIa introduces γ-glutamyl-ε-lysinyl covalent bonds between reactive glutamines and lysines in fibrin, which results in a tighter clot network that is resistant to fibrinolysis. Factor XIIIa crosslinks specific reactive glutamines on fibrinogen, selecting more reactive glutamines in the αC region of fibrinogen than any other chain. Although crosslinking pairs in the αC region have been identified, little is known about the extent of crosslinking and the role played …
